Didn't have Listerine for the Listering soak but this was just as cup apple cider vinegar, cup Epsom salt, cup baking soda, 10 drops lavender oil. UPDATE: I didn't have Epsom salt so I used coarse sea salt or lavender
DIY Remedy - Minimize mark that a blemish may leave by mixing teaspoon baking soda and teaspoon distilled water to create a paste. Apply to affected area for 5 minutes, splash off. After, use cotton swab to dab on hydrogen peroxide.
